show your working-out! :-)
Under the assumptions pointed out by rabidcow, below, and using the relations given in the puzzle (re-ordered, for convenience:)
(1) norwegian<-->first
(2) neighbor(norwegian,blue)
(3) red<-->brit
(4) green left of white
(5) yellow<-->dunhill
(6) neighbor (horses, dunhill)
(7) center<-->milk
(8 is arrived at in the deduction)
(9) green<-->coffee
(10) There is no (10).
(11) dane<-->tea
(12) bluemaster<-->beer
(13) neighbor(blends,water)
(14) german<-->prince
(15) pallmall<-->birds
(16) neighbor (blends, cats)
(17) swede<-->dog
we can deduce as follows:
house 1 house 2 house 3 house 4 house 5
============|=========|==============|================|===============
Norwegian(1)
blue(2)
(8) red/green(3,4) green/white(3,4) white/red(3,4)
so yellow
dunhill(5)
horses(6)
milk(7)
red (7,8,9) green white
coffee(9)
Brit (3)
not tea,beer(11,12)
so water
Blends(13)
not beer(12)
so tea
Dane(11)
beer (not needed
for solution)
not Bluemaster(12)
not Prince(14)
so Pallmall
birds(15)
cats(16)
not Bluemaster(12)
